Specs of BioBench Binary File Format

I'm interested in purchasing BioBench for a research project. I have a very limited budget. I'd like to collect the data with BioBench and access it directly, as the data files are likely to be quite large. I don't want to have to export to a text file first. Is the spec published so that I can write software to access it?
Thanks.
P.S. I know about the LabView VIs, but I don't own LabView and can't afford it!

Both BioBench and LabVIEW have a current base price of $995. As someone that has used both, LabVIEW offers far more functionality and adaptability than BioBench. It also has more File I/O and easier data access options than BioBench, which is more of a turn-key solution and can't be easily configured. Hope this helps.

Binary file format

Hello!
What is the binary file format for files created by Labview's example High
Speed Data Logger? The header information comes first, but how is the actual
logged data written in the file? I have logged two channels.
Thanks in advance for advice.
Best regards,
Antti Ryhänen

The LV code first converts the I16s to U16s and casts it as single-precision floats. It them multiplies the result by a scaling factor that's stored in the data header and adds an offset that's found in the same place.

Read doc file using the Word Binary file format

I want to be able to parse a Word file (xyz.doc).I want to be able to get to the actual text in the file and also get the "document properties" associated with this file.(This is the stuff you enter when you hit the File>>Properties button in Word)
I have the binary file format of MS word 6.0 and I suppose these "document properties" are stored within a segment in this file format.
Can anyone help me identify which segment in the Microsoft Binary word format this will be in???
(Ya and ofcourse I want to achieve all the parsing purely in Java!!..)
Thanks,
Supriya

IF you use MFC, yes. Don't ask how, this is the Java
forum. As to the JAva API, no. There is no API in Java
to deal with Microsoft docs, this is Java, not
Micorsoft. Ya I know that!!:P
You can write your own code, using the
information in the doc. The info you refer to is
locted on the header portion. As to how to read it,
best go to a Microsoft forum. Once you understand the
format, then post any Java related questions here,
i.e. how do I oppen a file to read/write etc. Good
luck, you will need patience, but you will leran a
lot...Thanks anyway for your reply!:)..Will try with patience

Labview binary file format, reading in matlab

Hi,
I have some binary files that I wrote in Labview containing data of type double. I'm trying to load the data in Matlab but I am not having much success. In Matlab I am using the fread command and specifying the type as double with the machine format as 'b' for big-endian. But the values I get do not make any sense. Does anyone know what format Labview saves the data in? Is it big-endian? Or something else?
Thanks,
Todd

LabVIEW stores data in BIG endian format. This was done to maintain compatability between all of the different platforms that LabVIEW runs on. And of course is an inheritance of the original Macintosh LV versions. There is a shipping documents that presents all the data storage formats. Just do a search in the LabVIEW bookshelf.

Binary file format to Ascii format

Hi,
I have a file in binary format in app server. I want to read the file in Binary mode and write that in legacy text mode. Problem here is... when I read that file in binary mode and passing to internal table. First record was fine from the second line carriage return(##) messing up my format. Anybody has any idea.
Thanks

hi, you can try some class like CL_ABAP_CONV_XXX, E.G. CL_ABAP_CONV_IN_CE.
some of them support us to convert Binary code convert into Text.

Parsing binary file- unsigned longs

Hello everyone.
I'm currently trying to write a quick parser for a binary file format (ASF). However, java's handling of bit shifting and lack of unsigned types is driving me completely mad.
How can I represent an unsigned long?
How can I set the bits for it anyway? It seems that the shift operator can't shift more than an int's worth (it just loops around and starts adding to the other bits- weird).
Thanks in advance.

But why in the world does the following code also do nothing?
long x = 45 << 32;
Try long x = 45L << 32;
The answer appears to be that java uses ints to represent all constants, but this presents some serious problems- namely- how on earth do you get a number bigger than an int into a long?With 'L'. Same as in C or C++. In Visual Basic it's '&'. There's generally something.Where did that come from? Why have I never seen anything like that before?
If I do long x = 0x7FFFFFFF; all is well, but if I do long x = 0x80000000; I get FFFFFFFF80000000, which isn't what I asked for.Actually it is exactly what you asked for. You've overlooked several facts: (i) Java longs are 64 bits; (ii) you specified a negative 32-bit constant; (iii) the rules of every programming language I can think of provide for sign-extension when going from a shorter to a longer type.Right. It makes sense now that I know how to specify long constants.
As someone pointed out signed/unsigned is actually the same, so long as you interpret it correctly. So to avoid the total stupidity of using twice as much memory for everything I've decided that I am actually going to use the correct types.They're not the correct types. As I pointed out in an earlier post, your 'unsigned longs' must be coming from C or C++ where they are generally 32 bits, so using a 64-bit Java long is incorrect.Where they came from doesn't matter. The spec doesn't say it's a "long"- it says that this particular value is 64bit, and that all values are unsigned. So I do need a Java long.
WHY IN THE WORLD IS JAVA "INTELLIGENT" WHEN DOING THINGS BITWISE? WHICH BRAIN DEAD IDIOT THOUGHT THAT UP? That is broken and is asking for trouble.It is you who is asking for trouble here. The rules of Java are consistent and in conformity with the practice in other programming languages. You've just overlooked several relevant facts.I think I've worked out where I was going wrong here. When doing something like
int i;
long x;
x = x | i;The i is converted to a long before the bitwise operation, so it's not the bitwise operation that's the problem, it's the conversion between int and long?
It's not Java whose stupidity is the issue here ;-)That wouldn't surprise me.
Thanks.

How can I read a binary file stream with many data type, as with AcqKnowledge physio binary data file?

I would like to read in and write physiological data files which were saved by BioPac�s AcqKnowledge 3.8.1 software, in conjunction with their MP150 acquisition system. To start with, I�d like to write a converter from different physiodata file format into the AcqKnowledge binary file format for version 3.5 � 3.7 (including 3.7.3). It will allow us to read different file format into an analysis package which can only read in file written by AcqKnowledge version 3.5 � 3.7 (including 3.7.3).
I attempted to write a reader following the Application Note AS156 entitled �AcqKnowledge File Format for PC with Windows� (see http://biopac.com/AppNotes/ app156Fi
leFormat/FileFormat.htm ). Note the link for the Mac File format is very instructive too - it is presented in a different style and might make sense to some people with C library like look (http://biopac.com/AppNotes/ app155macffmt/macff.htm).
I guess the problem I had was that I could not manage to read all the different byte data stream with File.vi. This is easy in C but I did not get very far in LabView 7.0. Also, I was a little unsure which LabView data types correspond to int, char , short, long, double, byte, RGB and Rect. And, since it is for PC I am also assuming the data to be written as �little endian� integer, and thus I also used byte swap vi.
Two samples *.acq binary files are attach to this post to the list. Demo.acq is for version 3.7-3.7.2, while SCR_EKGtest1b.acq was recorded and saved with AcqKnowledge 3.8.1, which version number is 41.
I would be grateful if you someone could explain how to handle such binary file stream with LabView and send an example to i
llustrate it.
Many thanks in advance for your help.

The reading of double is also straight forward : just use a dble float wired to the type cast node, after inverting the string (indian conversion).
See the attached example.
The measure of skin thickness is based on OCT (optical coherent tomography = interferometry) : an optical fiber system send and received light emitted to/back from the skin at a few centimeter distance. A profile of skin structure is then computed from the optical signal.

One more step...
short are U16 integer
double are double precision float
bool seem to be 2 bytes (= U16)
char are string (variable length)
rgb are U16 integer, with high order byte = 0
rect should be 4 x U16 (top, left, bottom, right)

The binary file processing in PDA device (LabVIEW PDA Module)

To whom it may concern,
I created a VI application, which should read some binary files and transform them to waveforms shown in the Waveform Graph. I implemented it with Mobile/PDA module. This application runs successfully on my desktop, that is, on the Labview Front Panel. However, when I run it on "Windows Mobile 5.0 Pocket PC Device" (a PDA has been already connected to the PC), all the windows, menus, buttons are displayed correctly, the only thing wrong is that the waveform can't be shown in the Waveform Graph. So, I wonder whether the Windows Mobile system will automatically modify the binary file format a little when I copy them from the PC to my PDA so that the original VI can't process it as what I expected in PC execution. Or, are there any requirements for the programs that will be executed in actual Windows Mobile Device?
Thanks a lot for any comments and suggestion.

Thanks, Jeremy,
I used LabVIEW 8.5.1. I rechecked and debugged the VI. The problem is not due to the Waveform Graph. I set an indicator after the Read File unit, in both PC Front Panel and PDA Front Panel. As I described before, when I run it in the PC Front Panel, the indicator could show the right values read from the file. But when I switch to PDA Device Front Panel, the indicator shows zero (invalid values), which demonstrate that the data is not accessed from original files.
The units I used are shown as follows:
File Dialog ---> Open/Create/Replace File ---> Get File Size ---> Read From Binary File (Here I set an indicator, no values read from the file, but if run in PC, correct values will be shown).
In this case, I guess the problem should come from the transfer (copy operation) of the file from PC to PDA. Or the operation behavior for LabVIEW Read File unit is a little different for PDA implementation from its PC implementation.
If you want more information, including the original binary file or VI, please let me know. Thanks a lot.

Binary file import and export in lab windows cvi

Hello,
I have some standard binary file format (.sie) that has been written in origin IDE. The sie type extension file format is a public format, but not defined by Origin. In origin IDE, i can be able to import these files and also be able to export it to excel as csv type. Now, i want to do the same thing in lab windows cvi. i need to import .sie type file and be able to read and export it to excel in lab windows cvi. Is this possible? Please help me to work on this project. Thanks in advance.
Regards,
Jayakumar.V

Reading and writing binary file is indeed possible in CVI, the problem normally lien in the definition of the file format you want to access.
I never found .SIE extension during my activity; a fast search on google returned this page with a link to the document explaining one file structure: it's a format dedicated to accounting so it's possibly not your case, but could they be your files?
Before finding the complete description of the file format you cannot think of any operation on the file itself, unless it is so self evident that you need little effort to access file content (this normally happens only on text files).
Proud to use LW/CVI from 3.1 on.

Binary file

hi
i write in labview to binary file the data is double i suppose the default mode is without any headers i have succed to read it back in labview
the problem is that i cant read the file from other places
in matlab i recieve garbage
fid = fopen(filename,'bin')
data = fread(fid,....)
fclose(fid)

The binary data that LabVIEW writes is going to be readable only by
LabVIEW because there is no "standard" binary file format. Each
application that can handle binary files has it's own method of
creating the file format.
If you want the data to be available to read in other applications, you
should save it as an ASCII (text) file. Most applications can read an
ASCII file is some standard format like comma separated values or tab
delimited files.
If writing speed is an issue, try first writting the files as binary, then convert them to ASCII when needed.

Where to find .abr (brushes) file format specification

Hi there,
I've found the "Adobe Photoshop File Formats Specification" in the documentation (http://www.adobe.com/devnet-apps/photoshop/fileformatashtml/).
But unfortunately it does not contain the spec for .abr brush file format.
Any ideas where to find this?
Thanks
Mirko

I don’t believe the current format is documented. It has a bunch of serialized ActionDescriptors inside, so documenting it fully and explicitly would probably be pretty difficult. If you use Photoshop’s code for parsing the ActionDescriptors though, you should be able to reverse engineer the format without impossible levels of effort – might take a couple days or something.

Binary JAR file format

Hi out there,
does anybody know where I can find the specification for the binary JAR file format?
It doesn't follow the ZIP spec, there must be some additions.
Here is my problem:
I'm reading the 1. local file header, there compressed and uncompresed size is 0. Bit 3 of the
general purpose bit flag is not set so there is no Data descriptor section and there should also be no
file data section (size is 0, extra field also 0). But there are still some
bytes until the next local file header starts. What are the bytes in between??
Somewhere in the middle of the 2 local file headers is the 0x08074b50 signature, which is mentioned
in the zip spec in combination with Spanned/Split archives !??
If I'm reading a ZIP file generated with WinZip it is working fine, but when I'm reading a jar generated with
the jar tool there are this mysterious bytes, which I cannot interpret.
Thanks in advance for your help.
Cheers,
Steffen

okay, guys just in case someone is interested (doesn't seem like, but anyhow):
YES, the jar tool is not sticking exactly to the zip specification. I found out when I was
browsing through the source code of the java distribution. The local file headers are not
filled with the size information!
Quote: * We'd like to initialize the sizes from the LOC, but unfortunately
* some ZIPs, including the jar command, don't put them there.The solution for it, which I think is the standard for zip processing anyhow, is reading the
central directory of the zip file first. There you get all info including also the size, etc. of the entries
and also the offset to the local file header.
The drawback is that it's a little more complex to read a file from the end and not from the beginning
because you have to find the beginning of the central directory first, but well ...
Okay, that's it. Have fun!

How to convert binary file to a particular format?

Hi,
I am having a requirement. I have in database various kinds of files stored as binary format. Its a sybase database. Now the files can be .pdf, or .doc also. But they are stored in binary format.
I need to read the file from database.
Now I can use jdbc to read the particular column value which contains the file in binary format.
But tricky part is how to convert the binary file entry in a proper respective file format? So I have another column which basically has the value to tell the type of file. So I have ".doc" or ".pdf" as each entry of file...
So please help me how can we do this using Java?
THanks

I can think of two possible stumbling blocks:
What are your 8.6 options for "byte order" and "prepend array or string size"?
Overall, many file IO functions have changed with LabVIEW 8.0, so there might not be an exact 1:1 code conversion. You might need to make some modifications. For example, in 7.1, you should use "write file", the "binary file VIs" are special purpose (I16 or SGL). What is your data type?
